what DOM events does jiffy track?

[Geuis]

I just heard about this via a list of Firebug extensions that was
posted on a blog. I'm actually very surprised, because jiffy is very
similar to a client-side reporting tool I have been developing for
about a month and a half on my own.

Looking through the documentation for jiffy, its not clearly posted
anywhere exactly which events are being tracked. Onload, unload, those
are stated. But what else does the tool track?

Seems interesting, might be some places I can contribute since its OSS.
